In principle, you can change your personal data saved in the hvv switch app at any time by simply logging into the hvv switch app and opening your customer profile. You can then change and save your data accordingly. Please note that altering certain data may result in it having to be verified once again, e.g. your mobile phone number or your chosen method of payment. The e-mail address saved for your account can never be changed. If you ever need to change such information, please contact our hvv switch customer service.
If you have successfully validated your driving licence, you can change your personal data and driving licence data via the app. However, this means that you will have to validate your driving licence again in order to be able to use providers that require a driving licence. You can change the address of your place of residence at any time without having to validate your driving licence again.
